The Lowdown
Alright, this is Rusty, and I’m looking at what’s on the table for the next couple of weeks. The water’s sitting at 73°, which is pretty much spot on average for this time of year, so no surprises there.
We’ve got a bit of a slow start, but things start to shape up from Wednesday morning. The first real standout window hits Wednesday the 5th and Thursday the 6th. Wednesday morning, Jaconé is looking clean with a light offshore breeze and a 3ft swell out of the south, period around 12 seconds. The energy is moderate (608), and the conditions are glassy – that’s about as good as it gets for a session where you don’t want to fight the wind. The swell direction lines up nicely with what this spot likes, so it’ll be peeling well. Just be aware, crowds are possible here sometimes.
Thursday morning the 6th brings a bigger pulse – 5ft swell from the east-northeast, but the period is short, only 7 seconds, so it’ll be a bit crumbly and less powerful. Still, with light offshore winds, it’s rideable and clean. The energy is moderate (433). After that, Friday and Saturday mornings are more of the same – clean, but the swell stays short-period and a bit inconsistent in quality.
Then we hit a lull. Saturday afternoon the 8th through to Tuesday the 11th is a mixed bag. The wind gets messy, and the swell energy jumps up (1523 on Saturday afternoon, 1556 on Sunday morning) but the wind turns cross-onshore or onshore, so it’s choppy and not worth paddling out for a quality session. Sunday afternoon the 9th is a real standout though – glassy conditions, 6ft swell from the south-southwest at 13 seconds, energy is strong (1214). This is a proper groundswell for experienced surfers, but it’s going to be a bit heavy and powerful, so not for the faint-hearted.
The second week kicks off with a solid run. Wednesday the 12th sees a drop in energy, but Thursday the 13th morning is a gem – 6ft south swell, 12 seconds, moderate offshore breeze from the east-northeast. The energy is moderate (915) but the wind is clean, so expect good shape. Friday the 14th and Saturday the 15th bring bigger stuff – 8ft and 8ft swells, long periods up to 15 seconds, but the wind is mostly cross-onshore or onshore, making it tough. Saturday afternoon the 15th stands out: 8ft from the south, 10 seconds, with a clean cross-offshore breeze. That’s big, powerful, and only for experts – the energy is strong (1259), and the wave face will be heaving.
Sunday the 16th morning is another standout – 8ft south swell, 14 seconds, with a moderate offshore breeze from the east-northeast. The energy is very strong (2215), and the conditions are clean. This is a big groundswell that’ll unload best at point breaks or reefs, but it’s all about the experienced crew. Monday the 17th morning eases off to 5ft, gentle offshore, and moderate energy (930) – a nice cleaner option if the big stuff is too much.
After that, Tuesday the 18th and Wednesday the 19th are weaker, with onshore winds and shorter period swells, not worth getting excited about. Thursday the 20th morning wraps it up with a 2ft south-southwest swell, 14 seconds, and gentle offshore wind – small but clean for a longboard session.
The clear standout for the whole period is Sunday afternoon the 9th – glassy, 6ft, long period, and excellent conditions for experienced surfers. For the second week, Thursday the 13th morning and Sunday the 16th morning are the ones to circle, but keep in mind the long-range stuff is a bit less certain. If you’re after clean, manageable waves, Wednesday the 5th and Monday the 17th mornings are your best bets.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
